May A Single Funeral Prayer Be Established For More Than One Deceased?

May a single funeral prayer be established for more than one deceased?

If more than one deceased is ready for burial, establishing a single prayer is enough for them although it is more appropriate to establish their prayers separately (Sarakhsi, al-Mabsut, II, 65; Mehmed Zihni, Ni‘met al-Islam, p. 591).
